JOHN A. RENNIE, OF LYNIDHUB-ST, NEW JERSEY, ASSIG-NOR TO UNDERWOOD TYPE- WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed December 3, 1910. Serial No. 595,333.

To all whom it may concern ing envelops to the platens of typewriting machines.

It has been usual to pack the envelops in a receptacle which has been mounted upon the letter-feeding carriage of the Writing machine; and the weight of the envelops as well as the weight of the receptacle itself, has proved a serious objection, because the weight of the carriage is so increased thereby that promptness in its letter-feedingaction has been sacrificed.

One of the main objects of the present invention is to overcomethis difficulty, and to that end I have contrived to'relieve the carriage altogether of the weight of the package of envelops and the envelop receptacle. This receptacle with its envelops I mount upon, or connect to, the stationary machine frame; and the carriage is thus not burdened with its weight, nor is the letter-feeding movement of the carriage retarded, by reason of the necessity of putting the extra mass into action at each letter-feeding operation.

In directing an envelop, it is customary to indent all lines after the first line of the address. Hence the paper carriage is moved back farther for beginning the first line of writing, than it is for beginning the succeeding lines. I have contrived a mechanism whereby when the paper carriage is moved back far enough to begin the first line of the address, an envelop is automatically picked up from. the pile or stack and fed into the machine. Hence the machine receives a new envelop as oftenas it is necessary to begin the writing of a first line. Therefore, the operator needs to pay no attention to the feeding of the envelops; suitable means being provided for carrying them through the machine in the required manner.

Since the-envelops and the receptacle are not carried upon the paper carriage, their weight is not limited, and hence it is practicable to place very many envelops in the receptacle, instead of the limited number which has heretofore been usual.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, Figure l is a front view of one form of the invention applied to the platenframe of an Underwood writing machine, the parts being in idle position. Fig. 2 shows the envelop inserted between the auxiliary feed rolls and the platen, ready to be fed to position to have the first line printed thereon. Fig. 3

is a side view, of the device partly broken away, the typewriting machine being shown in section. Fig. 4 is a detail plan of one end of the platen frame, showing the control of the auxiliaryfeed rolls by the linespace mechanism.

Types 1 strike against a platen 2 fixed to an axle 3 ournaled in the ends a of a platen frame 5, mounted on a carriage 6. Said carriage and platen are movable endwise in letterspacing direction and along a rail 7 secured to'the main frame 8. The platen has the usual rear and front feed rolls 9 and 9 and may be rotated either by turning the usual finger wheels 10 fast on the axle 3 or by a line-space lever 11 which operates a slide 12 having a pawl 13 to engage a linespace wheel is fast on the axle 3. Pressure against the lever 11 I turns the platen through one or more line spaces and returns the carriage 6 toward initial position.

An envelop receptacle comprising sides 15 and a bottom 16, is mounted upon a bracket 17 which may be secured to the frame 8 of the machine; whereby the carriage is relieved of the weight of the receptacle and its contents. This arrangement enables the receptacle to be made large enough to hold any desired number of envelops 18, which are placed between the sides 15 in inverted position with their flaps 19V to the front. The delivery end of the receptacle overhangs the platen frame, and a guard 20 partially closes said end to hold the stack of envelops against falling out.

Patented Sept. 7, 1915.

The bottom 16 of the receptacle is cut tom 16 of the receptacle, feeds the stack of envelops toward the delivery end.

The mechanism for extracting the envelops singly from the receptacle and supplying them to the carriage, is controlled by the carriage on its return movement to begin the first line of a new address.

As the carriage approaches initial position (Fig. 1) the left-hand end 4 of the platen frame strikes a tappet on the free end of a feed lever-25 pivoted at 26 preferably to an car 27 on the envelop receptacle. The feed lever or arm 25 communicates motion to a short arm 28 having a pin and slot connection 29, 30 with the feed lever.

The arm 28 is fast on a shaft 31, journaled in ears 32 on the receptacle. The comparatively slight rotation of the shaft 31 swings downwardly a motion-multiplying arm 33 secured to the shaft, and having a link 34, connecting it with a vibratory frame, which comprises a cross bar 35, vi brating in front of the guard 20. Said frame has slides 36 at its opposite ends mounted on upstanding guides 37, at opposite sides of the delivery end of the recepta cle. Ejectors 3S depend from the frame 35, and a downward movement of the frame inserts the lower ends of said ejectors under the flap 19 of the foremost inverted envelop 18 (which for this purpose is caused to protrude through an opening 23 between the guard 20 and the bottom 16 of the receptacle by the pressure of the follower 21 against the rear end of the stack of envelops), to thrust said envelop through the discharge opening 24. By the time the carriage reaches initial position, the envelop has been thrust downwardly behind the platen, (Fig. 2), the frame 35 being arrested by the con tact of the slides 36 with stops 39 on the guides 37. 1

An auxiliary feed roll mechanism may be provided to assure the advance of the en velop to the usual feed rolls 9. Auxiliary feed rolls 40 engage the rear face of the platen 2, such rolls being journaled on a shaft 41 fast in arms 42 of a frame 43 pivoted on the usual tie rod 44 connecting the platen frame ends 4.

Returning the carriage toward initial position by pressing the line space lever 11 forces the slide 12rearwardly. A lip 45 on the slide (Fig. 4) then strikes a link 46 pivoted by a slot 47 and pin 48 (Fig. 3) to the inner face of the left hand platen frame end 4, the rear end of the link being hinged to the outer end of the shaft 41, to swing the frame 43 and cast 05 the auxiliary feed rolls 40. The shaft 41 is fixed against turning in the arms 42, as by having one end squared and fitted in a corresponding aperture in one of said arms as at 55 (Fig. 1). The

rolls are released prior to the operation of the ejecting mechanism and lie out of the path of the leading edge of the envelop 18 which is advanced by the ejectors 38 to a plane below the rolls The s acing lever 11. is released the moment the carriage reaches its initial position i (Fig. 2), whereupon the slide 12 is returned to normal position by the usual spring 49, and a returning spring 50 causes the auxiliary feed rolls 40 to press the envelop 18 against the platen. By turning the finger wheels 10, the platen is rotated to advance the leading edge of the envelop downwardly to the bite of the rear feed rolls 9 and platen after which a continued turning of the platen feeds the envelop in the usual manner.

The first line of the address is now written, the carriage being fed in letter-spacing direction, at each type stroke, thereby enabling a returning spring 51 to raise the ejecting frame and swing the feed lever 25 back to normal position (Fig. 1). Stops 53 arrest the frame 35 in normal position. The first line having been written, pressure against the lever 11 advances the envelop and returns the carriage to position to commence the second line of the address. Said second line, however, is begun with the carriage a short distance to the left of its initial position so that the ejecting mechanism is not actuated at this time. The auxiliary feed rolls 40 may, in some cases, be omitted.

Though my invention has been illustrated and described in detail as it is adapted to be used in feeding envelops, it is obvious that various portions of it may be used in feeding devices for cards, sheets and other work pieces. So the word envelop which is used for convenience and brevity throughout the specification, is to be understood in every instance as covering such cards, sheets and other work pieces as far as the structure of the parts then under consideration is applicable to handling such cards, etc.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
